AI Technical Summary
Technical Problem
In traditional welding methods, incomplete or excessive welding can easily occur between the welding strip and the busbar, and incomplete welding is difficult to detect, which affects the photoelectric conversion efficiency of solar cells.
Method used
A groove for shaping the welding strip is set on the second pad of the welding device, and a magnet layer is set on the surface of the groove. A constant magnetic field is formed in conjunction with the electromagnetic flowmeter, and the output signal of the electromagnetic flowmeter is used to determine whether the welding strip is poorly welded.
Benefits of technology
This improves the reliability of welding and the accuracy of detecting incomplete welds, ensuring the stability and reliability of welding.
